TIRE-PATCH.

Specification of Letters latent.

Application filed April 28, 1913.

Patented May 12, 1914. Serial No. 764,014..

I To all whom it ma-y concern Be it known that I, WILLIAM C. Howaan, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Tire-Patches, of which the following is a specification.

My invention relates to improvements in pneumatic-tirepatches, and my object is to prov-idea simple device of this character which may be employed to advantage in closing punctures too large to be sealed with the rubber plugs usually employed for that purpose.

The invention is particularly adapted for use in emergencies arising from punctures or blow-outs while on the road, and may be readily applied with the aid of only an ordinary wrench. r

The device embodies means for closing punctures both in the inner and outer tubes of the tire, and in orderthat the invention may be fully understood, reference will now be made to. the accompanying drawing, in which-- Figure l is a longitudinal section on line 'II of Fig. 9, of the outer portion of atire with my patch applied thereto. Fig. 2 is a detail perspective of a nut employed in holding the patch in place. Fig. 3 is a detail perspective of an outer clamping-plate constituting part of the device. V Fig. 4 is a nut employed in holding several parts of the de vice together. Fig. 5 is a detail perspective of a toothed-plate -forming an important feature of the device. Fig. 6 is a cross section on line VI-VI of Fig. 9. Fig. 7 is a detail'perspective of an inner clampingplate. Fig. 8.is a detail perspective of a bolt used in securing the several parts of the patch in place. Fig. 9 is a broken plan view of a tire with the patch applied thereto. Fig. 10 is a modified form of patch applied to a tire.

Referring now in detail to the parts disclosed by the drawing, A designates the outer tube and B the inner tube of an automobile tire, said tubes being punctured at C and D, respectively.

. 1 designates an outer clamping-plate having a central opening 2 therein.

3 designates an inner clamping-plate having teeth 4 struck upward from the margin thereof, and a rectangular central opening 5.

6 designates an inner clamping-plate having a rectangular central opening As shown on F igs. l and 6, the clampingplates are curved to fit the contour of the tire when the same is inflated.

8 designates a bolt having a head 9 at one end and a rectangular shoulder 10 adjacent said head.

11 designates a nut having a central threaded opening and a threaded tubular extension 12 to receive the threaded portion of bolt 8.

13 designates a nut adapted to be screwed v upon bolt 8. As shown the nuts 11 and 13 are thinner and wider than the customary nuts. This is. for the purpose of coverin a comparatively wide surface without taking up much room lengthwise of the bolt 8.

11, 15, 16 and 17 designate, respectively, sheets of canvas or other suitable material of substantially the same shape as the plates 1, 3 and 6, which as shown are of elliptical form, although I do not restrict myself to this particular form as it is obvious that plates of oval or other form may be employed to advantage.

18 designates a soft or raw rubber sheet applied to one side of plate 6.

In practice, the canvas sheet 17, the inner plate 6 and its rubber sheet 18 are slip d upon the bolt 8 in the order mentioned a ter which said bolt is placed through the puncture D, in the inner tube B. The canvas sheets 16 and 15, and the toothed-plate 3, are then slipped upon the bolt 8, in the order named after which the nut 13 is placed upon the bolt 8, and screwed up against the toothed-plate 3 until the whole is firmly bound together. The canvas sheet 14 is then slipped over nut 13 and the teeth 4;, until it rests against the adjacent surface of plate 3. The threaded end of bolt 8 is next placed through the puncture C in the outer tube A, and the outer clamping-plate l is slipped over the end of bolt 8 and against said outer tube A, after which nut 11 is screwed upon the bolt until all of the parts are firmly clamped together. The screwing up of nut 11 upon bolt 8 embeds teeth 4 in the tube A, so that the material surrounding the puncture C is reliably held from spreading and allowing said puncture to enlarge when the tire is inflated and subjected to heavy pressure incident to traveling over a road.

The rubber and canvas sheets prevent the air from escaping around the bolt 8, or between the tire tubes and the clamping-plates 3 and 6, and also prevent such Wear to the tubes as would occur if said clamping-plates came directly in contact therewith. The clamping'plates aremade in different sizes to accommodate large or small punctures,

tubes.

fied form, A designates the tire, 1 the outerclamping-plate, 8 the bolt, and 11 the outer nut.

Having thus described my invention, what I claim and desire to secure by Letters Patent is: y

1. In combination with a tire having inner and outer tubes, a plate to engage the .Iouter surface of the outer tube, a plate to engage-the inner surface of the outer tube and theadjacent surface of the inner tube,

a platetoengage the inner surface'of the inner,v tube, and means extending through openings in said tubes to firmly draw the plates against the adjacent surfaces of the 2. In combination with a tire having inner and outer tubes, a plate to engage the outer surface of the outer tube, a toothedplate to engage the inner surface of the outer tube and the adjacent surface of the inner tube, a plate to engage the inner surface of the inner tube, a bolt extending through the tubes and said plates, a nut threaded on said bolt to firmly draw the inner tube and adjacent plates firmly together, and a nut engaging the outer end of said bolt andthe outer plate to draw the whole firmly together and embed the teeth in the outer tube.

3. In combination with a tire having inner and outer tubes, a plate to engage the of the inner tube, a clamping plate placed against the last-mentioned sheet, and means to draw the Whole firmly together and ,embed the teeth in the outer tube.

In testimony whereof I affix my signature, in the presence of two witnesses.
